*mlm Corne ZV-ius WMe ers A BYWy/Qj Patented June 9, 1953 UNITED STATES. PATENT OFFICE 2,641,3sc COLLAPSIBLE POURING sPoT Cornelius W. Meyers, Portland, Oreg?. Application August 13, 194s, serial Nn. 44,131 s Claims. (o1. 22a- 501) `My invention. pertains to pouring spouts, and relates particularly to a collapsible pouring spout which may be readily inserted in the bung hole of a barrel and may be pushed into said barrel when not in use.

It. is a principal object of my invention to provide a collapsible pouring spout made of rubber or other flexible material and which may be removably inserted in the bung hole of a barrel for dispensing liquids therefrom. y

Another object is the provision of a pouring spout which may be attached to the bung hole cap, whereby said pouring spout may be stored within the barrel when not in use and may be inserted in said bung hole by pulling outwardly onsaid cap. n

Other objects and advantages of my invention will appear from the following detailed description taken in connection with the accompanying drawing in which:

Fig'. l is a plan View, partially in section, illustrating the structural features of a pouring spout embodying my invention; v

Fig. 2 is an elevation taken along the line 2`2 of' Eig'. l, parts being broken away to show struc-l tural details of the pouring spout outlet and the plugvalve Fig. 3 is a sectional view taken along the line 4er-41 oi l;

Fig. 4. is a sectional view similar to Fig, 3 illustrating. the manner in which the pouring spout is folded or collapsed preparatory to insertion in the bung hole of a barrel; and y Eig. 5 isa section taken along the line 5 5 of Figi. l, showing the manner in which the valve stem is secured to the bung hole cap'.

The, pouring spout. embodying my invention comprises a flexible cylindrical body I molded of rubber lor similar resilient. material. `A partition 2 is formed,l transversely in said. cylinder at a distance from the closed end 34 thereof, and a portion of the body I between the partition and' the, closed end is` cut. away to. form a discharge spout 4i through. which the liquid contained-f thefbarrel'. may be dispensed..

in aperture 5 is formed in. the. partition in the: shape of a truncated cone which tapersJ inwardly towardthe. dischargesnoutli. A conical valve 6 of hard rubber or other substantially rigid material is constructiedrand arranged tebe releasably seated in said apertureI 5. One end 0E' a. valve. rod. l is. moldedinto orJ otherwise securely attached to the valve and extends out# wardly through a 'hole 8 formed in the closed end 3 of the body. To the termnial end of the valve rod is secured a Us'haped fitting 9. A'pin ID extending transversely through said fitting engages a loop I I which is secured to the bung hole cap I2. The cap is thus plvotally connected to the valve. E, and the latter may be pulled into and pushed away from the aperture 5 by manipulating the cap. *f

The intermediate portion I3 of the body I is of smaller diameter than the open end portion Il. These sections are joined by a smooth surfaced tapered portion I5 which affords easy insertion of the body into the bung hole I6 of the valve I1. The end portion I4 has an outward diameter slightly greater than the diameter of the bung hole in order to provide a snug compressive nt. and a positive seal therebetween. A shoulder I8 extends circumferentially about the end portion I4 to form a stop and a sealing flange between the inner wall of the barrel and the body I, thereby' to prevent leakage of liquid from the barrel. The top portion t9 of said shoulder, i. e.' the portion diametrically opposite the discharge spout 4,' is preferably cut off to decrease the resistance of said shoulder topressure applied when it is; desired. to collapse the body, as explained hereinafter. In addition, slots Z0 are out in said shoulder on opposite sides o1 the top portion I9 to reduce the elastic strength of the shoulder and permit easy distortion of the body during collapsing of the latter.

In installingl the pouring. spout in the barrel after the bung hole cap lf2 has vbeen attached to the valve rod. 1.,; tlnnnb pressureis applied upon the reduced: top portion I 9 of the shoulder I8: until the open end. of the body I collapses to the shape illustrated in 4 of the drawing. The bod-y is'thus. reduced' in outside.` dimension sunlorenilly to. permit, insertion in the bung hole. I6.` When., the body has been; inserted in thev bung hole the. hand pressure is: relaxed and. the body springs outwardly from its collapsed condition to the arrangement shown4 in. Fia.r 3.. Ordinarily the pouring spout will be: pushed. into the barrel and: the cap, i2IA secured. in. place"l preparatory to lstripping the. barreland itsy contents to the. consum-er; In. thisfmanner the barrel isV equipped' with `a pouring spoutv which is: when the cap is removed'.-

When it. isi desired to. remove liquid from the barret. the. latter is rested onend and the cap |12 is; unthreaded from the bung hole I6. vWhen the cap` is pulled outwardly from thev barrel the valve rod I is drawn outwardly through the hole Band the valve 6 moves into the aperture 5. By virtue of the conical shape of the valve the latter readily available is readily centered in the aperture. When the valve has been seated rmly in the aperture 5 further pull on the cap I2 causes the body I to be drawn outwardly through the bung hole. When the tapered portion I5 of the body engages the peripheral wall defining the bung hole additional pulling force is required in order to draw the enlarged portion I 4 into the hole. By moving the body in a see-saw fashion or wiggling it simultaneously while pulling thereon, the former is drawn into and seated in the hole. 'I'he raised shoulder I8 abuts against the inner margin of the bung hole and prevents complete withdrawal and separation of the body from the barrel. .The pouring spout embodying my invention is now its side upon a suitable support. l,

In drawing liquid from the barrel the cap I2 is pushed inwardly toward the barrelto unseat the valve 6 and provide passage of liquid through the aperture 5. 'I'he area `ol the aperture may be varied, to regulate the volume of discharge from the barrel, by moving the valve selected distances away from the aperture. When the liquid has been withdrawn the cap I2 is pulled outwardly to bring the valve into register with the aperture and seat the valve therein, thereby to stop the ow of liquid from the barrel.

After the contents of the barrel have been removed, or it is otherwise desired to seal the barrel, the latter is placed on end and the cap I2 is pushed inwardly toward the barrel, Substantial force is required to unseat the pouring spout from .the bunghole and cause it to fall into the barrel. This force may be minimized by collapsing the body, as described hereinbefore, to reduce its outside diameter and thus 'draw it away from Contact with the threaded bung hole. The pouring spout may be pushed into the barrel and to be housed wholely therein where it hangs suspended from the cap I2, which is secured in the bung hole. If for any reason it is desired to remove the pouring spout from the barrel the body I is collapsed according to the procedure previously described. With the diameter of the body and shoulder I8, thus reduced suliiciently to pass through the bung hole, the pouring spout is readily withdrawn.

I claim:
